A bottom supporting shelf allocation and management system for rows of products includes adjacent shelf allocating and managing units. Each unit includes a shelf supported base supporting at least one row of products, and a perpendicular side divider extending vertically above the base. The side divider is removeably attached to a base side edge where the coupling locks the side divider and base in a fixed lateral and vertical position but enables the side divider to manually slide forward and backward along the base. A backstop is attached to the rear of the side divider protruding laterally across the base. The backstop, when the side divider is manually brought forward, makes contact with a rearmost product resting on the base and will push the rearmost product and any other products on the base forward in sympathy with the forward movement of the side divider.

An adjustable chute structure is provided, which includes at least one chute and two cross beams disposed at two ends of the chute. Each end of the chute is connected with a chute plug, which is slidably mounted on the cross beams and is provided with a receiving groove. The receiving groove is provided with a movable switch, and a first mating member and a second mating member coupled with the movable switch. The cross beams are provided with a plurality of first limiting members arranged consecutively in a lengthwise direction, and the chute engages or plug-fits with the first limiting member through the first mating member to be fixed transversely between the cross beams. Each cross beam is provided with a second limiting member, and the chute is interlocked and connected with the second limiting member through the second mating member to be fixed longitudinally to the cross beams.

A goods presentation system includes a storage area on which a row of articles is to be arranged one behind the other. The storage area extends towards a removal position at which a foremost article of the row is to be removed from the storage area. A separating element that is displaceable between first and second positions includes front and back parts spaced apart from one another. The front part hinders removal of the foremost article from the storage area when the separating element is in the first position and permits removal thereof when the separating element is in the second position. The back part hinders another article of the row arranged on the storage area behind the foremost article from moving towards the removal position when the separating element is in the second position.
